1. Cut energy costs up to 50%. For improved lab efficiency air flow monitors check the fume hood face velocity & help to insure that the proper amount of room air changes per hour are maintained. The sash stop is designed for user protection and cfm reduction, allowing the sash to open to a maximum position of half open. With an average utility rate of $7.00 per cfm a typical annual savings on a 4’fume hood would be $2705.00 on a 6’ fume hood $4067.00.

2. Sash should only set to full open position for the set up of tall apparatus. Personal safety protection should be worn as recommended by the Lab Safety Officer.

3. When the fume hood is not in use return the sash to the closed position.


Fume Hood Face Velocity cfm

The recommended face velocity for efficiency & safety should be 80-100 fpm. Lower face velocity may compromise user safety.

Sash in full open position should be for setup of apparatus & maintenance service only. If opening is at 1/2 open at 100 fpm (feet per minute), face
velocity at full open would be approximately 50 fpm.
